CVE-2025-61417
📋 TL;DR
A stored Cross-Site Scripting (XSS) vulnerability in TastyIgniter's media manager allows attackers to upload malicious SVG files containing JavaScript. When an administrator previews these files, the code executes in their browser context, potentially enabling account takeover or unauthorized administrative actions. This affects TastyIgniter 3.7.7 installations with admin access to the media manager.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the TastyIgniter admin panel, allowing attackers to modify admin credentials, inject backdoors, steal sensitive data, or take full control of the application.
Likely Case
Attackers gain administrative privileges by modifying admin account credentials through XSS payloads, leading to unauthorized access and potential data exfiltration.
If Mitigated
Limited impact if proper file upload validation and content security policies are implemented, preventing SVG execution or restricting admin preview functionality.
🎯 Exploit Status
Exploitation requires an attacker to upload a malicious SVG file and trick an admin into previewing it. The GitHub reference includes proof-of-concept details.
🛠️ Fix & Mitigation
✅ Official Fix

🔧 Temporary Workarounds
Disable SVG uploads
allConfigure the media manager to block SVG file uploads entirely.
Modify TastyIgniter configuration to restrict allowed file types, removing SVG from the list.
Implement Content Security Policy (CSP)
allAdd CSP headers to prevent inline script execution in SVG files.
Add 'Content-Security-Policy: script-src 'self'' to HTTP headers.
🧯 If You Can't Patch
- Restrict admin access to trusted IP addresses only.
- Disable the media manager preview functionality for SVG files.
🔍 How to Verify
Check if Vulnerable:
Check if TastyIgniter version is 3.7.7 and test by uploading an SVG with simple JavaScript (e.g., <svg><script>alert('XSS')</script></svg>) and previewing it as admin.Check Version:
Check TastyIgniter version in admin panel or via application files.Verify Fix Applied:
After patching, attempt the same SVG upload and preview test; JavaScript should not execute.📡 Detection & Monitoring
